A bracket includes a fixing piece on a rotation element ( 3 ), said fixing piece comprising a body ( 22 ) in the general form of a ring, provided with an annular radial projection ( 23 ). The body includes an opening ( 33 ) which permits a variation in the diameter of said body ( 22 ) on assembly with engagement of the projection ( 23 ) in a corresponding groove ( 9 ) on the rotation element ( 3 ) to give a radial interference fit. A bar ( 28 ) prevents a variation in the diameter of the body ( 22 ) as above after the assembly thereof. |
